You can submit the patent application yourself, or you can ask a third-party agency to do it for you.

You need to write your own patent information when you submit it, and you are not familiar with the main points of patent application, so it is easy to lose the owner.

When applying for an agency, you can choose a powerful and experienced agent to write, which can help you with patent funding and the price is also applicable. A while ago, an old friend applied for an invention patent, and the acceptance notice was quickly taken down to the person who was applying for a patent. Choose your own agent, just compare more.
